Release Notes

modelcontextprotocol/go-sdk (github.com/modelcontextprotocol/go-sdk)

v1.3.1

Compare Source

This release is a patch release for v1.3.0.

It contains a cherry-pick for a security issue reported in #​805, which takes advantage of the default behavior of Go's standard library JSON decoder that allows case-insensitive matches to struct field names (or "json" tags). The issue has been addressed by changing the JSON decoder to one that supports case sensitive matching.

Fixes

• all: use case-sensitive JSON unmarshaling by @​maciej-kisiel in #​807

New external dependencies

• https://github.com/segmentio/encoding, which is the package that provides the new decoder.
